Set the number of rings-to-answer
When the answer mode is set to Automatic, the product rings-to-answer setting determines the number
of times the telephone rings before the product answers an incoming call.
If the product is connected to a line that receives both fax and voice calls (a shared line) and that also
uses an answering machine, you might need to adjust the rings-to-answer setting. The number of rings-
to-answer for the product must be greater than the rings-to-answer on the answering machine. This
allows the answering machine to answer the incoming call and record a message if it is a voice call.
When the answering machine answers the call, the product listens to the call and automatically answers
it if it detects fax tones.
The default setting for rings-to-answer is five for the U.S. and Canada, and two for other countries/
regions.
Use the following table to determine the number of rings-to-answer to use.
Type of telephone line Recommended rings-to-answer setting
Dedicated fax line (receiving only fax calls) Set to a number of rings within the range shown on the control-
panel display. (The minimum and maximum number of rings
allowed varies by country/region.)
One line with two separate numbers and a ring-pattern service One or two rings. (If you have an answering machine or
computer voicemail for the other telephone number, make sure
that the product is set to a greater number of rings than the
answering system. Also, use the distinctive-ring feature to
differentiate between voice and fax calls.)
Shared line (receiving both fax and voice calls) with only an
attached telephone
Five rings or more.
Shared line (receiving both fax and voice calls) with an
attached answering machine or computer voicemail
Two rings more than the answering machine or computer
voicemail.
